Algae or something else?
Hello everyone, I have a question if this is algae or something else in my loop. Water blocks are a ek copper ek supremacy evo and ek full coverage nickel plated copper acetal 980ti water blocks. I have always been using distilled water with drops of PT nuke mixed in. I added a new RAM kit and to do this I needed 30mm extensions on CPU for clearance of tubing over the dominators. I checked my cpu and also notice blackish deep brown on my glass reservoir. I'll link the pictures and let me know what I should do next.
